I'm sorry to hear your pain . I would suggest getting imaging that tests your ligaments while in motion . This is xalked DMX
Digital motion X-ray . A movie of your back in motion . A ton of radiation for sure
However you need to find out what the
Problem is . Sacro-occipital blocks
If back is out of alignment can torque
Your discs back into place . Prolotherapy
User ultrasound or flouroscipic
Guidence may be helpful as well .
